May I ask why you feel that this would be a useful feature?  I have a
hard time understanding it since it's not something I can see myself
wanting to do.

Generally speaking, if a buffer extends beyond the window to the right,
I just never see that text, which in some sense is the same as if the
column had been narrowed.  And if there's extra room in the window, it
might as well be used for something instead of just being empty.
